Great work MRVass and everyone, coming back here only recently I wondered where the images had all gone, now I know. I see the forum has a favicon too, I was only thinking it would be nice to have one yesterday now that I've pinned ES as a Firefox Tab. :D Any chance of getting ATOM/RSS so I can...

That radial pattern while good for lateral loads (cornering) is not good for torsional load (braking/accelerating). I'd have gone with a cross pattern and 48 spokes, especially with such large rotors and the 108kg you're stopping. If anyone is interested in actual brake performance data, then...

Came across these from Voltage Cycles. The Board Tracker was also at Interbike under the Pedego branding. Board Tracker Classic Cruiser Chopper vm8coPPRCwc

IEEE Spectrum have an article about DC in the data center and I noticed the sparkless plugs which would be great for helping prevent Kentucky Fried Fingers as well as other accidents. Anyone know of any suitable for ebikes?

Thanks guys, I think I have a much better understanding now. Take a look at the following small brushed PMDC motor speed-torque efficiency chart and please tell me if I'm reading it correctly. It's a little backwards. To begin with I was a little confused as to where it lists the motor torque...

Hi Jeremy, Thanks for your knowledge here, lots of useful info there, however I think I should have been clearer. :oops: I'm a relative newbie at motor design and reading these charts, so please correct me if anything that follows is incorrect. What I'm really interested in is how low an...

I found another I'm adding to the list. Golden Motor have data for a heavy 11 Kg BLDC for 3-7.5 KW that appears to be around 72-87 Kv. The efficiency shown on the performance curve doesn't match their performance sheet (the rpm indicates different motors). Nor does it show the low rpm torque...

Damn that's expensive for the prototype's laser cutting and bonding, as you say only really makes sense then to make them in numbers if you can find the demand. You never know who might find a use for it if you wanted to market it.

Electrons take turns like pedestrians I hate to think how hard ES peeps are pushing those little electrons through their own DIY constrictions. :P

Thanks for the data Ryan. Looks like a great project, keep us informed if you do the rewind! What are your plans for the motor?

Anyone thought about autonomous ebiking? or etriking? What would you use a small automonous bike/trike sized vehicle to do? KpHGSLsTpCY 6CYGT97i8qU

Nice tutorial. Especially like the shrink wrap needle. :arrow: Which has more copper area now? The 10 AWG or the 8 x ?? AWG phase wire?

Thanks Jeremy. I remembered I should have mentioned that after I wrote the damn post... :lol: Hindsight! It's always behind you.

If you've ever held a bicycle wheel in your hands and spun it at speed, you'll have felt the resistance to change in direction. I've often wondered how the flywheel KERS affects the cars change in direction and handling. I'm sure they could use this to their benefit if they wanted to... :wink...
